Ideally your first cycle should be test only.

Test is a natural hormone so adverse effects should be less and when you run more complicated cycles in the future you will know how each new compound is effecting your cycle.

If you're bulking then the stack you chose was a poor choice.

Mast is a muscle conditioner and is best used at low body fat because it will have little effect on new muscle tissue.

Imo you should run a test only cycle along with and AI, hcg and a nolva clomid PCT.

During your first cycle it's also important to have mid cycle blood work so that you can hone in your AI dose to keep your e2 within range.
